在一次MCP通话中运行多个bash步骤，判断每个步骤是否都达到了你的预期效果。

退出代码为零仅证明命令已执行。使用 omega_batch，每一步都可以携带 expect 断言（contains / notContains / regex]。每一步报告为 ok、FAIL (process) 或 FAIL (expectation)，退出代码、信号、超时和 stderr 保持独立。失败后跳过的步骤会显示为 (halted)，而非无声消失。

零 npm 依赖。节点 >= 20。支持任何讲标准的 MCP 主机（Claude Code、opencode、Claude Desktop 等）。

安装

克劳德代码：

Generic JSON config （[mcpServers）：

opencode（opencode.json， mcp 部分）：

然后呼叫omega_health一次。第一行是结论（[HEALTHY / DEGRADED）;缺少的可选部分显示为[--]。

示例

omega_batch 等待判决（最多到 waitMs，默认 45 秒），并在同一通电话中回答。成功是一行：

失败时会显示出口代码和输出的尾，其中错误为：

• expect 与 full 输出进行检查。输出超过 4000 字符时，会发送到 artifact:// 参考。

batch-runner-mcp

Run several bash steps in one MCP call, and know whether each one actually did what you wanted.

A zero exit code only proves a command ran. With omega_batch, every step can carry an expect assertion (contains / notContains / regex). Each step is reported as ok, FAIL (process) or FAIL (expectation), with exit code, signal, timeout and stderr kept separate. Steps skipped after a failure are listed as (halted) instead of silently disappearing.

Zero npm dependencies. Node >= 20. Works with any MCP host that speaks stdio (Claude Code, opencode, Claude Desktop, …).

Install

Claude Code:

claude mcp add batch-runner -- npx -y github:Birdywen/batch-runner-mcp

Generic JSON config (mcpServers):

{ "batch-runner": { "command": "npx", "args": ["-y", "github:Birdywen/batch-runner-mcp"] } }

opencode (opencode.json, mcp section):

{ "batch-runner": { "type": "local", "command": ["npx", "-y", "github:Birdywen/batch-runner-mcp"] } }

Then call omega_health once. The first line is the verdict (HEALTHY / DEGRADED); optional parts that are missing show as [--].

Example

{ "steps": [
  { "label": "build", "command_line": "npm run build", "expect": { "contains": ["compiled successfully"] } },
  { "label": "smoke", "command_line": "node dist/cli.js --version", "env": { "NO_COLOR": "1" }, "expect": { "regex": "^\\d+\\.\\d+" } }
], "stopOnError": true }

omega_batch waits for the verdict (up to waitMs, default 45s) and answers in the same call. Success is one line:

batch job-xxxx: success 2/2 (3.1s): build | smoke

A failure shows the exit code and the tail of the output, where errors are:

batch job-xxxx: failed 1/2 (0.4s)
  [FAIL] 1. build (process)
      exit=2
      src/a.ts(3,7): error TS2322: Type 'string' is not assignable to type 'number'.
  [--] 2. (halted) -- stopOnError

• expect is checked against the full output. Output over 4000 chars goes to an artifact:// ref.
• Still running after waitMs: the reply has the job id; omega_batch_status {id, waitMs} picks it up. cancel: true kills the running step’s process group.
• Job state is on disk after every step; after a restart an unfinished job reads as interrupted.
• format: "json" gives structured per-step fields; verbose: true adds output.
